Answer : The correct option is, 7.58

Explanation : Given,

pOH = 6.42

pH : It is defined as the negative logarithm of the hydrogen ion concentration.

As we know that,

pH+pOH=14

Now put the value of pOH in this expression, we get the pH of this solution.

pH+pOH=14

pH+6.42=14

pH=14-6.42

pH=7.58

Therefore, the pH of this solution is, 7.58

What is the formula of the compound formed between chlorine and calcium?
VLD [36.1K]

the formula  of the compound that  is formed  between  chlorine and calcium  is CaCl2


explanation

chlorine (non  metal)  react  with Calcium ( a metal)  to  form an ionic compound  CaCl2

Ionic compound   is formed when metal  loses electrons to form cation ( a  positively charged ion)  while  non metal  gains electrons  to  form anion (  a  negatively  charged ion)

An ionic compound is formed when calcium   metal(Ca) loses two electron to form   Ca2+ cation ,  while   2 chlorine atom  gain  one electron each to form cl- anions.


  • when writing  down  the formula  of ionic compound  cation  symbol  is written first  followed by  anion symbol.

Therefore the formula  of ionic compound formed between chlorine  and calcium is CaCl2
